To all whom it may concern:

Be it known that I, IVAN LEVINS EIN, a subject of the King of Great Britam and Ireland, and a resident of Manchester, 1n the county of Lancaster, England, have invented a new and useful Preparation of Sulfo Compounds of Hydrogenized' Fats and Oils and of Compositions Therewith, of which the following is a specification.

This invention relates to the production of compounds from hydrogenized saponifiable fats or oils and to the production therewith of compositions from Waxes, fats, oils, or the like, which are soluble, miscible, or emulsifiable in water without the addition ofalkali. I The compositions obtained are valuable in the preparation and treatment of leather,

and in the textile industries, as special finishes.

In carrying this invention into effect hardened oils obtained by the hydrogenization of saponifiable' fats or oils, such, for example, as hardened fish oil or har-- dened linseed oil, are treated under certain conditions with sulfuric acid. The sulfo compounds so obtained have the remarkable property of making mineral and other waxes, oils, fats, or the like (herein referred to for convenience as waxes) soluble, miscible or emulsifiable in water.

In order to obtain these sulfo compounds I take, say, hardened linseed oil, and after melting it treat it with sulfuric acid until a sample from the mass gives an emulsion with water, or until a washed sample practically dissolves in ammoniacal water. The mass is then Will separate in the form of a white pulpy mass.

The following is an example of how a sulfo compound may be produced according (100% H 80 monohydrate preferred) are, then added gradually and the temperatureis kept between 40-45 C. until a washed sample is practically soluble in hot water.

poured into water previouslyheated to 30 (1, when the sulfo'compound,

Patented May 30,1916.

Application filed January 20, 1915. Serial No. 3,383.

The whole is then run into a salt solution (10 Tw.) which has-been heated to a temperature of 30 C.,'-is well stirred, and then allowed to settle, after which the salt water drawn off. The washing with salt water 1s again repeated untilthe mineral acid-has been removed, or the mineral acid may be neutralized with alkali. The sulfo acid of hardened linseed oil thus obtained when melted and mixed with equal parts of paraflin wax gives a composition which ticallysoluble'in hot water without dition. of alkali.

The hardened oils can be snlfonated when is practhe ad' mixed with oils or greases, but the remarkable property possessed by the product of.

making waxes miscible or soluble or emulsifiable in water without neutralizing the sulfo acid or without any addition of alkali, appears to be to some extent diminished.

What I claim is -1. The preparation of sulfo compounds of hydrogenized fats or oils, which consists in melting the hardened oils obtained by the hydrogenization of saponifiable fats or oils,

cooling them, treating them with sulfuric acid until a sample gives an emulsion with hot water, and pouring the mass into a salt solution of about 30 C. when the sulfo compound separates in the form of a white pulpy mass, substantially as hereinbefore described. Y

2. The preparation which are soluble, in hot water fron. waxes which consists in first melting the hardened oils obtained by the hydrogenization of saponifiable fats or oils, cooling them, treating them with sulof compositions miscible or emulsifiable furic acid until a sample gives an emulsion .with 'hot water and pouring the massinto a I salt solution of about 30 degrees centigrade, when the sulfo'compound separates in the and mixing form of a white pulpy mass,

with equal the sulfo compound obtained .parts of melted wax, substantially as set forth.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
